Wog Native Dialogues has a different round number (in the battle log) with ERA (v997) when the tactics phase is active

If the tactics phase is active, instead of starting from round 0, the battle log shows it starts from round 1, the value is different from v997 (1 more).
If the tactics phase is inactive, round 1 is shown on the second turn of the battle, value is the same with v997.
It would be better to standardise the numbers here, keeping the round number equal to v997 (or v997 plus one) to avoid confusion.
